2008 PONTIAC SOLSTICE differential

Traction Control Operation
Traction control limits wheel spin by reducing engine
power to the wheels (engine speed management)
and by applying brakes to each individual wheel
(brake-traction control) as necessary.
The traction control system is enabled automatically
when you start your vehicle, and it will activate and ash
the ESC/TCS light and display the LOW TRACTION
message if it senses that any of the wheels are spinning
or beginning to lose traction while driving. For more
information on the LOW TRACTION message,
seeDriver Information Center (DIC) on page 3-37.
Notice:If you allow the wheel(s) of one axle to
spin excessively while the ESC/TCS, ABS and
Brake warning lights and the SERVICE ESC and/or
SERVICE TRACTION messages are displayed, you
could damage the differential. The repairs would not
be covered by your warranty. Reduce engine power
and do not spin the wheel(s) excessively while these
lights and this message are displayed.Notice:When traction control is turned off, or
Competitive Driving Mode is active, it is possible
to lose traction. If you attempt to shift with the
rear wheels spinning with a loss of traction, it is
possible to cause damage to the transmission.
Do not attempt to shift when the rear wheels do
not have traction. Damage caused by misuse of
the vehicle is not covered. See your warranty
book for additional information.
The traction control system may activate on dry or rough
roads or under conditions such as heavy acceleration
while turning or abrupt upshifts/downshifts of the
transmission. When this happens, you may notice
a reduction in acceleration, or may hear a noise or
vibration. This is normal.
If your vehicle is in cruise control when the system
activates, the ESC/TCS light will ash and the cruise
control will automatically disengage. When road
conditions allow you to use cruise control again,
you may re-engage the cruise control. SeeCruise
Control on page 3-10.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.

Limited-Slip Rear Axle
Your vehicle may have a limited-slip rear differential
which provides maximum power and performance.
It is designed to give you additional traction on snow,
mud, ice, sand or gravel. It works like a standard
axle most of the time, but when one of the rear wheels
has no traction and the other does, this feature will
allow the wheel with traction to move the vehicle.
During a sudden shift, such as shifting from FIRST (1)
to SECOND (2) gear at low engine speeds or suddenly
applying the clutch, you may feel or hear a clunking
or rattling noise. This is normal.
Electronic Stability Control (ESC)
Your vehicle may have an Electronic Stability Control
(ESC) system which combines antilock brake, and
traction and stability control systems that help the
driver maintain directional control of the vehicle in
most driving conditions.
When the vehicle is started and begins to move, the
system performs several diagnostic checks to ensure
there are no problems. You may hear or feel the system
working. This is normal and does not mean there is a
problem with your vehicle. The system should initialize
before the vehicle reaches 20 mph (32 km/h).If the system fails to turn on or activate, the ESC/TCS
light comes on, and the ESC OFF and/or SERVICE ESC
message displays.
For more information, seeDriver Information
Center (DIC) on page 3-37andElectronic Stability
Control (ESC)/Traction Control System (TCS)
Indicator/Warning Light on page 3-29.
This light ashes on the
instrument panel cluster
while the ESC system is
on and activated.
ESC activates when the computer senses a discrepancy
between your intended path and the direction the vehicle
is actually traveling. ESC selectively applies braking
pressure at any one of the vehicle’s brakes to help steer
the vehicle in the direction which you are steering.
